Hello,
google.com found this:
The Intel-syntax conversion instructions
* cbw -- sign-extend byte in %al to word in %ax,
* cwde -- sign-extend word in %ax to long in %eax,
* cwd -- sign-extend word in %ax to long in %dx:%ax,
* cdq -- sign-extend dword in %eax to quad in %edx:%eax,
* cdqe -- sign-extend dword in %eax to quad in %rax (x86-64 only),
* cdo -- sign-extend quad in %rax to octuple in %rdx:%rax (x86-64 only)
are called cbtw, cwtl, cwtd, cltd, cltq, and cqto in AT&T naming. as as
^^^^^
accepts either naming for these instructions.
